Abstract
The self‐regenerative property of LaCo1–x –yPdx Zny O3±δ and LaFe1–x –yPdx Zny O3±δ solid solutions with monometallic Pd or bimetallic Pd/Zn substituents for Co or Fe is studied under a redox cycle by high angular annular dark‐field scanning transmission electron microscopy (STEM‐HAADF) and energy dispersive X‐ray spectroscopy (EDX) and X‐ray diffraction (XRD). These results reveal that the composition of perovskites determines the self‐regenerative property that occurs largely in LaCo1–x –yPdx Zny O3±δ but is limited greatly in LaFe1–x –yPdx Zny O3±δ.
